Sorry for late reply,
So earlier today, I went into the “manage save”menu and viewed the list of players in my game. As of now I have 5 players that have all been saved on the list and one of them was last online 218 days ago. I wasn’t sure if I could invite more than the 4 people I already had so I pressed delete on the inactive players account. Upon loading my save and viewing the in game player menu, the inactive players account was still there and my friend who’s username was not even close to the other account in the menu, had been deleted instead. I’m just curious if there is some sort of profile recovery that could be helped with or done remotely by support because I imagine my friend will not want to come back and play since this glitch deleted his progress. Any help is appreciated.
